A laboratory notebook records what was done, what was observed and how the work can be traced. Its value comes from giving a future reader enough context to understand the evidence, including the person who did the work and has since forgotten the details.
That matters from school practical learning to university research and technical careers. A clear final report explains a conclusion; the underlying record helps someone follow the route to it. This guide introduces that distinction through a fictional measurement example.
The choices at a glance
| Route | Purpose | Useful first check |
|---|---|---|
| School practical learning | Record an activity and its observations | Teacher instructions and relevant units |
| University research | Maintain traceable project records | Institutional policy and the data management plan |
| Collaboration | Help another authorised reader understand | Context, permissions and approved storage |
| Technical careers | Explain evidence and hand over work | The workplace's actual procedures |

CHAPTER 1 OF 10 · Understand the purpose and the actual work
1. Give the record a job beyond helping you remember
“I will remember what this means” is a brave promise to make beside an unexplained spreadsheet. A week later, three files named “final” may have a different opinion.
A useful record helps answer a defined question: which activity produced this observation, under which conditions, and how was it used? A notebook can point to associated data files, approved procedures and calculations without containing every item itself.
Follow the format required by the teacher, supervisor or institution. Paper and electronic systems have different practical features, but neither makes an unclear record reliable merely by existing.
CHAPTER 2 OF 10 · Understand the purpose and the actual work
2. Separate a plan from what actually happened
Before work begins, state the question, intended method and relevant approved procedure. During the work, record what actually happened, including departures from the plan through the authorised process.
A plan might say that three readings will be taken. The record might show that only two were obtained before an equipment problem. Those are different facts, and both matter.
Do not fill the missing reading with a plausible number. Record the gap and ask the responsible teaching or research staff how to proceed. A smaller honest dataset gives a reader a sounder starting point than an invented complete one.
CHAPTER 3 OF 10 · Identify readings and show calculations
3. Identify the observation clearly
Consider this fictional teaching record: a student measures the same marked length three times and writes “12, 13, 12”.
We do not yet know the unit, object, instrument, reading convention or conditions. The numbers look orderly, but they are difficult to interpret.
A more useful entry identifies the task and records readings of 12 cm, 13 cm and 12 cm, with the actual instrument and relevant conditions. In a real activity, include the information required by the course or approved procedure. Do not invent an instrument resolution after the event because the report needs one.
CHAPTER 4 OF 10 · Identify readings and show calculations
4. Keep observations and calculations connected
For the fictional values, the arithmetic mean is (12 + 13 + 12) ÷ 3 = 37 ÷ 3 cm, approximately 12.33 cm before any reporting convention is applied.
That calculation does not establish that the true length is 12.33 cm. Instrument capability, measurement method, uncertainty and the course's reporting rules still matter. More decimal places in a calculator do not create more information in the readings.
Preserve the original values and show the calculation separately. If you later discover a transcription error, use the approved correction process so the original entry and change remain traceable. Avoid silently replacing the observation with the result you expected.
CHAPTER 5 OF 10 · Investigate exceptions and check institutional rules
5. Record an unexpected result before explaining it away
Suppose a fourth fictional entry reads 21 cm. The student suspects that 12 was copied backwards. Suspicion is a reason to check the source record, not permission to rewrite the value.
If an original instrument record confirms a transcription error, document the correction appropriately. If the value was actually observed, investigate the method and conditions with the responsible teacher or supervisor.
A reason for excluding data needs to be stated and justified under the applicable method. “It spoils the average” does not explain why a reading is invalid. The record should let a reader distinguish an error, an unexplained observation and a justified analytical choice.
CHAPTER 6 OF 10 · Investigate exceptions and check institutional rules
6. Understand the Singapore research context
NTU's Research Integrity Policy links research data management with a Data Management Plan, retention and deposition. It explicitly includes laboratory notebooks within research output to be maintained under its policy.
That is an institutional example of records having responsibilities beyond an individual's convenience. The policy also addresses research integrity in collaboration and credits contributions.
Students and researchers should check their own institution's current policies, project agreements and supervisor instructions. A retention period or storage arrangement at one institution should not be copied into another project without checking.
CHAPTER 7 OF 10 · Support collaboration and independent explanation
7. Make collaboration possible without oversharing
A collaborator needs enough context to understand a dataset, but access must follow the project's permissions. Clear labels, agreed units and an explanation of variables help people work together across disciplines and countries.
Before sharing, establish who is authorised to receive the material and which approved system to use. Research records may contain confidential, personal, commercial or otherwise restricted information.
A screenshot pasted into a public portfolio may remove the controls that existed in the original system. Use an approved non-sensitive example when explaining your learning outside the project, and ask before sharing actual records.
CHAPTER 8 OF 10 · Support collaboration and independent explanation
8. Use the record to explain and learn
After an activity, try explaining the question, method, main observation and limitation without reading every entry aloud. Then check the notebook and repair any mistaken recollection.
The purpose is understanding the process. It does not replace recording observations at the appropriate time. Reconstructing details from memory after the event is a different activity from documenting what happened.
Across a career, a similar habit helps with technical handovers and quality records: explain where information came from and which decision it supports. The required systems and standards still depend on the workplace.
CHAPTER 9 OF 10 · Repair an entry and answer common questions
9. Practise repairing an incomplete entry
Here is a fictional entry: “Repeated test. Better result. Mean 12.3. See file.”
Identify the gaps before improving the prose. What was tested? What does “better” mean? Where are the individual readings and units? Which exact file is linked? Was the method the same as before?
Using the stated fictional values from Chapter 4, a student can show the arithmetic, identify the unit and link the calculation to the three readings. Information that was never provided must remain unknown; do not fabricate a date, instrument or condition.
For a fresh task, imagine measurements of time instead of length. Which parts of the record remain useful, and which details need changing? The unit, method and relevant conditions must fit the new activity. Later, explain those choices again without relying on the original example.
CHAPTER 10 OF 10 · Repair an entry and answer common questions
10. Questions students and new researchers ask
Is a notebook the same as a final laboratory report?
They serve related purposes. A report presents an organised account and interpretation. The underlying record documents the work and connects it with evidence. Follow the course requirements for each.
Can a photograph replace written notes?
A photograph may support a record if permitted and linked to its context. It may not show the method, timing, units or decision being documented. Ask what the approved process requires.
Should every unusual result be removed?
No. Record it, check the source and investigate appropriately. Any exclusion needs a defensible reason under the applicable method.
Does this guide authorise a laboratory activity?
No. Actual practical work requires the teaching, supervision, training and approvals of the responsible institution. The worked example here concerns documentation and arithmetic.
